Efficient and Secure communication in Vehicular Ad hoc Network
International Journal of Computer Applications
Recent advances in development of Wireless Communication in Vehicular Adhoc Network (VANET) has provided Emerging platform for researchers. VANET are movable & fixed infrastructure. One of the main challenges in VANET is to secure communication. VANET is a open network for all and different types of attacker available for attack to victims node in the network & create problem in communication. Denial of services (DOS) and DDOS are very destructive for security system as well as authentication
... as authentication and Privacy are big challenges, finally we designed DOS prevention algorithm, Which is capable secure communication. Keywords Attacker, Attacks, victims node, DOS, DDOS etc. 2) Messages thereby jamming the channel, 3) Delay in passing the information, 4) Dropping the information packet etc. TYPES OF ATTACKERS IN VANET Different types of attacker in VANET create security problem. Some attackers act in different time during communication and harm the valuable information which may directly affect the vehicles and may lead to jam, accidents etc.
